11) Emma lived in Louisiana and her sister, Estela, lived in Mississippi. It was late March and they were congratulating themselves for mailing their income tax returns before the deadline. In their conversation, they learned that they each had the same income and paid the same state income tax. In Louisiana, the state income tax was $70 plus 6% income over $25,000. In Mississippi, the state income tax was $1000 plus 5% of the income over $25,000. Find each sister's income and the amount of state income tax they paid.
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
